5) Hand wash
To make sure that your bra does not get ruined but still feels perfectly sanitized, you can consider hand-washing it using baking soda, which has 2 benefits. On the one hand, it deodorizes the garments, and on the other hand, it sanitizes them without being aggressive. Just dissolve 100 grams of baking soda in 2 liters of warm water and you’re done.
